SPECIFICATION forming part of Letters Patent No. 265,112, dated September 26, 1.882.

Application filed July 12, 1882.

To all whom it may concern Be it known that we, HENRY S. LORD and CORNELIUS BIRKERY, of Hartford,in the county of Hartford and State of Connecticut, have invented a new Improvementin Water-Closet Valves; and we do hereby declare the following, when taken in connection 'with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in v Figure l, a vertical central section enlarged;

Fig. 2, a section on line m or, looking up; Fig.

1 3, a horizontal section, showing the adaptation ot' the valve to the Hartford Sanitary Plumbing Uompanys closet.

This invention relates to an improvement in the valve for admitting or cutting 0d the sup- 2o ply of water to the bowl of a water-closet, and particularly to the valve employed in the closet of the well-known Hartford Sanitary Plumbing 00., and such as shown in Fig. 3, in which a is the inlet or water-supply passage, 1; the

2 5 passage to the bowl. 0 is the valve arranged to close the passage 0 and cutoff thetlow of water thereto. The valve is hung to a flexible diaphragm, d, and through the valveis a small passage, c, through which water may flow from 0 the main passage at until a pressure above the valve is established equal to the pressure from below. From the chamber f, above the diaphragm, a passage, h, leads to the waste t, and

a in this passage is a valve, l, which is closed by 5 means of a float, m, hung upon a lever, a, the float hanging in a chamber adjacent to the how], so that when the water in the bowl has reached a certain elevation the float will be raised and turn the lever a so as to close the valve 1; but when the water is permitted to escape from the bowl, then the float m falls and opens the valve 1, and consequently the passage from the chamber f above the diaphragm d. Supposing the valve 0 to be in its closed 4 5 position, the valve I also closed, then when the water is permitted to escape from the bowl the float will fall and open the valve 1, relieving the valve 0 from the balancing-pressure close'the passage to the bowl.

above. Immediately the pressure from the passage 0t upon the under side of the valve 0 causes it to rise, as seen in broken lines Fig. 3, and the water toflow through the passage 1) to the bowl. The small opening into the chamber f is no greater than the escape-passage trom the chamherf. Hence the water, which 5 will naturally flow into the chamberf, will escape therefrom and the valve 0 be held open and the flow continue to the bowl until the water in the bowl shall rise to the predetermined point, which will act upon the float m. Then the float will rise and close the valve Z so as to prevent the flow of water from the cliamberf. Then the water will continue to flow through the passage to and into the cham berf until the'pressure in the chamber above the diaphragm produces an equilibrium, which will cause the valve 0 to fall upon its seat and The pressure of the water is then upon the top of the valve. This construction of valve is too well-known to require more detailed description, and is substantially the construction of valve and escape of the water to produce equilibrium as used in various closets. A serious difficulty arises in the use of these valves owing to the 7 necessarily small aperture through which the water escapes to produce the equilibrium upon the valve, these small openings being liable to be choked or stopped by foreign substances in the water, and when so stoppedre- 8o quire a plumber to clear them. Another difficulty existing in the use of this class of valves is the hammering in the pipes. It

the chamber directly above the valve be filled too quicklythat is, under high pressure-it throws thevalve back onto its seat,causing the inflow to instantly stop, and produces what is called hammering in all the connecting pipes.

The object of this invention is to overcome these difliculties; and it consists in the arrangement of a valve in the escape-passage which will, when the pressure of water is admitted, nearly close that passage, leavingonly the required escape, but when at rest will en- 5 tirely open the passage, so that a considerable flow of water will pass around and upon the valve to clear the passages should foreign substances enter therein, and as more fully hereinafter described.

In order to better illustrate the invention, we show the valve enlarged to twice the full size in Fig. 1, in which A represents the valve 0 of Fig. A passage, or several openings,B, are made through the valve above its face, entering into the chamber D, into which chamber the escape-passage 6 opens into the chamber f above the diaphragm d. In the chamber D is a valve, E, which rests below the lower end of the passage 0, and distant therefrom, so as to leave clearconnection from the chamber 1) to the passage 0. Around the lower end of the passage 0 is a downwardlyprojecting flange, 1", (see Fig. 3,) and in this flange notches s, more or less in number, are made. When the water is admitted, as before described, it flows above the valve A through the passages B,and beneath the valve E,causing that valve to rise and stand against the flange r, around the passage, asseenin broken lines, Fig. 1. This closes that passage, except as to the one or more notches s, and so that the only escape of water through the passage the passage 0 and leaves the notches s free, so

that the next flow of Water will necessarily wash those notches and theirsurroundingsbefore the valveE can be raised to contract that passage to the notches s. The valve E, when it rises and strikes the lower end of the passage 0, will tend to start from that part of the water-way any obstructions which may have lodged therein. By this construction we are enabled to contract the escape to the smallest possible extent without danger of that small escape becoming clogged.

By the employment ofthe valve E,in connection with the free open passage 6, the hammering is avoided, because the first inflow of serves as a cushion to resist the reaction of the sudden inflow of water.

As before stated, while designed with special reference to the Hartford Sanitary Plumbing (Jompanys closet, this valve may be employed in connection withmauy of the closets which close the inflow of water by an equilibrium produced upon the valve.

While we prefer to make the notches s i the lowerend of or flange surrounding the passage e, they may be made in the face of the valve, it only being essential that the valve shall be soarrauged as to partially close the passage 0 when the water is admitted and open that passage when the water is cut off.

We claim 1. The combination of the valve by which the flow to the bowl is opened and closed, an escape-passage from above the valve, a valve arranged to operate in connection with said escape-passage to partially close the said passage when the flow of water is admitted and open said passage when the flow is cut off, substantially as described.

2. The valve A, constructed with Water-passages B, into a chamber, D, the escape-passage e,opening into said chamber D,thevalve E, arranged in said chamber and below the passage e,the said valve arranged topartiall y close the said passage 0 when the water is admitted and open said passage when the flow is cut off, substantially as described.
